Conduction Through Viscoelastic Phase in a Redox-Active Ionic Liquid at Reduced Temperatures

Thorsmolle, Verner K.; Topgaard, Daniel LU ; Brauer, Jan C.; Zakeeruddin, Shaik M.; Lindman, Björn LU ; Graetzel, Michael and Moser, Jacques-E. (2012) In Advanced Materials 24(6). p.781-781
Abstract
The phase diagram of the redox active ionic liquid 1-methyl-3-propylimidazolium iodide (PMII) is examined as a function of temperature and iodine concentration. Beyond a threshold concentration of 3.9 M, the formation of higher polyiodides gives rise to a viscoelastic phase upon cooling. Despite of the very high viscosity of such polyiodide-containing PMII melts a strikingly high conductivity is maintained through Grotthuss-type bond exchange and ionic conduction.
